6 Claims.

This invention relates to improvements in gunsights.

One object of this invention is to provide an improved gun-sight construction including a telescopic-sight and an ordinary rear-sight, both so mounted as to be selectivelyshiftable into and out of the normal line of sight without the need of detaching either sight from the gun.

Another object of this invention is to provide an improved gun-sight construction formed of simple elements readily manufactured and readily assembled to produce a durable, eflicient construction at minimum cost.

With the above and other objects in view, this invention includes all improvements over the prior art which are disclosed in this application.

In the accompanying drawings, in which one way of carrying out the invention is shown for illustrative purposes:

Fig. 1 is a side elevation of a gun illustrating one embodiment of an improved gun-sight construction made in accordance with this invention;

Fig. 2 is an enlarged side elevation of a. portion of Fig. 1, with the sighting elements occupying different positions from those shown in Fig. 1;

Fig. 3 is a right-end elevation of Fig. 2;

Fig. 4 is a view similar to Fig. 3, but with the sighting members moved to positions corresponding to those they occupy in Fig. 1;

Fig. 5 is an enlarged vertical sectional view of the rear peep-sight construction on the plane indicated by line 55 of Fig. 1;

Fig. 6 is a horizontal sectional view on the plane indicated by line 6-6 of Fig. 5;

Fig. 7 is a perspective view of the two main supporting parts of the rear peep-sight construction;

Fig. 8 is a rear perspective view of the clickspring; and

Fig. 9 is a horizontal sectional view on line 9--9 of Fig. 2.

In the description and claims, the various parts are identified by specific names for convenience, but they are intended to be as generic in their application as the prior art will permit.

Referring to the drawings, the receiver 20 is detachably mounted on the stock 2| of the gun and detachably receives the rear end of the barrel 22. Secured to the receiver 20 in any suitable way, as by screws 23, is a rear peep-sight base 24 having a threaded opening 25 and a coaxial, upstanding, cylindrical opening 26, in which opening 26 a stem or sight-supporting member 21 is mounted for horizontal rotation and up-anddown sliding movements. The stem 2'! has a cylindrical opening 28 which houses a coil-spring 29 under endwise compression and down through which coil-spring 29 extends a stud 30 having its lower end 3| screw-threadedly engaged in the screw-threaded opening 25. Rigidly secured to 5 or formed integral with the stem 21 is a horizontally-extending bar or shank 32 having a cylindrical opening 33 extending out through one end of the shank 32, and having opposite openings 34 and 35 extending out through opposite 10 side-walls 36 and 37 respectively.

An adjusting-pin 38 has a cylindrical head 39 slidably mounted in the cylindrical opening 33, and a reduced shank-portion 40 extending through a coil-spring 4| under endwise compres- 15 sion, and having its screw-threaded end 42 threadedly engaged by the adjusting-nut or knob 43.

The head 39 has a transverse screw-threaded opening 44 adapted to be threadedly engaged 2 by the screw-threaded shank 45 of a rear sightmember such as the peep-sight member 46, which latter has an annular shoulder or flange 41 adapted to abut against the outer face of the wall 36 when the shank 45 of the sight-member is en- 25 gaged in the threaded opening 44.

A cliclgsprjngjfl is secured by screws 49 and 56 to the stem 21 and has a spring-arm 5| provided with a click-point or boss 52 adapted to resiliently snap into and out of the notches 53 30 in the adjusting-head 54, and also has a second spring-arm 55 provided with a click-point or boss 56 adapted to resiliently snap into and out of notches 5'! of the adjusting-nut 43.

The base 24 is cut away at 58 (Fig. '7) to pro- 35 vide two limit-shoulders 59 and 60, which are adapted to be engaged by a limit-pin 6|, rigidly secured to the bar or shank 32. The base 24 has a threaded opening 62 (Fig. 5) in which is threadedly engaged the threaded shank of a set- 40 screw 63. A coil-spring 64 is under compression between the base 24 and the head of the setscrew 63.

The telescopic-sight construction includes a bracket 65 secured by screws 66 to the receiver 26. 45 The bracket 65 is provided with a dovetailed guide-slot construction 61 in which adjustably slides the longitudinally-split tang 68 of a telescopic sight-carrying bracket 69. A bolt 10 has a conical head ll (Fig. 9) engaged in a conical 50 opening 12 formed midway of the split tang 68. The head H has secured therein a pin 13 which lies within the longitudinal slot 14 of the split tang 68 to prevent rotation of the bolt 10 relative to the tang 68. The outer threaded end 15 of the 55 bolt 16 is threadedly engaged by a lever-nut 16 which is adapted to be turned to press against the washer 11 to draw the conical head 1| against the walls of the conical opening 12 and spread apart the parts of the tang 68 on opposite sides of the slot 14 so as to jam the tang 68 against the walls of the dovetailed slot 61, to thus lock the tang in any desired vertically-adjusted position. The telescopic-sight-carrying bracket 69 carries the telescopic-sight 16 therein for angular adjustment both vertically and horizontally in a manner well-known in the art.

For ordinary shooting, where the rear peepsight 46 is to be used, the lever-nut 16 is loosened and the telescopic-sight-carrying bracket 69, with its telescope I8, is raised from the position shown in Figs. 1 and 4 to that shown in Figs. 2 and 3, whereupon the lever-nut is again tightened to hold the bracket 69 and tang 68 in the elevated position. Then, the set-screw 63 is loosened and the sleeve 21 is rotated in a horizontal plane to swing the peep-sight member 46 from the position shown in Figs. 1 and 4, and in solid lines in Fig. 6. to the position shown in Figs. 2 and 3, and in dotted lines in Fig. 6, thus causing the limit-pin 6| to move away from the limit-shoulder 59 (Fig. '7) and engage against the limit-shoulder 60, whereupon the set-screw 63 is tightened to hold the rear peep-sight in adjusted position for sighting.

If the sight is to be adjusted for elevation, the set-screw 63 is loosened and the adjusting-head 54 is rotated in one direction or the other until the click-spring 48 snaps past the desired number of notches 53 to correspondingly raise the bolt 30 and result in the stem 21 being raised by the spring 29, or lower the bolt 36 and force the stem down against the action of the spring 39, whereupon the set-screw 63 is again tightened.

If adjustment is to be made for windage, the adjusting-nut 43 is rotated in one direction or the other to cause the bolt 38, together with the peep-sight 46 carried thereby, to be correspondingly adjusted in one direction or the other, depending upon the direction of the wind. I

If it is then desired to use the telescopic sight instead of the rear peep-sight, the set-screw 63 is loosened and the stem 21 is rotated from the position shown in Figs. 2 and 3, and in dotted lines in Fig. 6, to that shown in Figs. 1 and 4, and in solid lines in Fig. 6, thus moving the peepsight out of and sufliciently away from the line of sight to permit the telescopic-sight-carrying bracket 69 and its telescopic-sight I8 to be moved down to bring the telescopic-sight close to the gun-receiver or barrel of the gun and substantially in the normal line of sight of the gun.

The invention may be carried out in other specific ways than that herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiment is therefore to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
